The Sysselman's sentry was an officer stationed outside of the Sysselman's house in Trollesund. His dæmon was a husky dog. When the panserbjørn Iorek Byrnison found out where the townspeople had hidden his armour, the sentry pursued him in an attempt to stop him. He entered the priest's house to stop the bear, but came back out to get reinforcements. He was attacked and almost killed by Iorek, but Lyra Silvertongue stopped Iorek just in time.
